WATER-CLOSET.

' Application filed July 17,

To all whom it may concern Be it known that I, WINFIELD E. Hms DALE, acitizen of the United States, residing at Trenton, in the county ofMercer and State of New Jersey, have invented a certain new and usefulImprovement in Water-Closets, of which the following is a specification.

My present invention mentsin'water-closets, and more especially toclosets of'the siphon jet type.

The invention is directed particularly to improvements in existing typesof siphon jet water-closets, and has for one of its objects theincorporation, integrally with the bowl and general closet structure, ofa vent duct of large area and, at the same time, to retain a s mmetricalshape and to avoid distortion o thecomplete closet by the incorporatedchambers and water-ways or pas sages. V

In designing such a structure, it should be borne in mind that certainfeatures in common use, such as the meansprovided for attaching theseat, have become more or less staple or standardized, and the fact thatmakers of special seats have adopted certain and fixed measurementsmakes it impera tive that such a design conform to the traderequirements in order to obviate the necessity of providing specialtrimmings an consequently enhancing the cost thereof.

, Furthermore, it is desirable, if in fact not necessary, that little,if any, departure be made from what has grown, by years of use and thepractice ofall makers, to be the standardmeasurement of a closet,both'as to height and width.

A still further object of the invention resides inthe provisionofspecial ways for the introduction of the water into the flushing rimand to the jet opening; also in the provision of special water ducts oropenings for flushing the walls of the vent duct;

The arrangement of the channels or conduits which convey the water tothe fiushing rim is such that all the contained air in the waterpassages or conduits above the water-level in the bowl will be drivenahead of the falling water from the flushing device, without in any waymixing said confined air with the following or advancing Specificationof Letters Patent.

water, thus eliminating all noise caused by the mixing of air and waterunder pressure.

It is evident from what has been said that in order to bring about theintroduction of a vent duct and the necessary water ways or channelswithin the confines of a standard closet, changes must be made in thewater ways, both as to inlet and outlet, and that the vent duct itselfmust be kept below the plane of the rim of the bowl until well clear ofthe portion of the closet that is intimate to the user.

Two embodiments of the invention are disclosed in the annexed drawings,wherein:

Figure 1 is a vertical sectional view of the closet having a local orrear vent of large area;

Fig. 2 a vertical sectional view, the plane of section at the left beingon the'line I-I, and that to the right being on the line 11-11 of Fig.1;

Fig. 3 a sectional plan view, the section being on the line IIIIII ofFig. 1;

Fig. 4 a vertical sectional view, showing arrangement wherein the ventduct is omitted, but the other features are retained; and

Fig. 5 a transverse detail sectional view, on the line V-V of Fig. 4.

Referring first to Figs. 1 to 3 inclusive, it willbe seen that thecloset is formed as a with the various-ducts and water-ways therein.

The bowl proper is denoted generally by 1', and surmounts a base'orpedestal 2. The vent duct is designated by 3, the inner portion whereofopens directly into the bowl, said inner portion lying below the upperface of the bowl (denoted by 4) and terminating between the se aratedrear ends of aid rim, as will be noted upon reference to Figs. 1 and 3(see also Fig. 5) is not continuous and the space between its ends isbridged over by a curved and receding lip 6, which is not as deep as therim, but merges into the same. By

' omitting the usual flushing rim for a space over an inch, thusremoving this portion of foulable surface in its entirety.

To the rear of the seat hinge-post holes 7 duct 3 extends upwardly andrearwardly,

terminating in a mouth or spigot 8. Pockets 9 are provided in the sidewalls of the closet, or the vent duct, beneath the holes 7, whichpockets, while enlarging the vent duct, also afford a ready means forsecuring thenuts upon the inner ends of the seat hinge-posts.Furthermore, the retaining nuts will be inclosed, thus eliminating theusual and un-' went duct, and the omission of .the-usual-rear portionof-the'flushing rim 5 necessitates a rearrangement of the water ductsand passages. I The water supply from theusual tank ,or reservoir:enters the regular topinlet or condait 10, from which extend branches orways 11, which passdownwa-rdly and slightly {onward and .open inwardlyinto a chamber or recess 12 underlying the bottom .of the trapvandprovided with'the usual jet orifice or opening 13. Each of thevertically-disposed ways 11 is in communication with ahorizontally-disposed way 14, the forward end of which turns upwardly,as at '15, and opens into the adjacent rear end of the flushing rim 5.

A plurality of openings 16 will preferabl-y be provided through the wallbetween the upper portion of the vent 3 and the condu'it 10, tothoroughly flush .or wash down I the'wallsof the vent duct at eachoperation of the closet. V I

Thetrap and siphon outlet ofthe closet are denoted by 17 and 18, whichlatter terminates in the usual outlet nozzle '19.

From the foregoing it is thought that the advantages accruing from theconstruction will appear to those skilled in the art, but it maybe wellto set them forth in a [general wav.

'Heretofore, ivent ducts have been .made integral with the closetandconneoted to the "bowl by means of one or more openings extendingthrough the bowl wall and under the edge of the continuous flushing rim,producing an uncleanable pocket back of .the

-*bowl surface and out of reach of the flushing water.

With the construction above set forth I amrena-bled toprovide a localiorrear vent which 'has a clear and free opening extending from the bowl tot'hetstack and which in a closet of-standard dimensions may be of 1. 1,iour-inch -diameter. Furthermore, the

.;9, is washed down by from the opening 1.6,

of the flushing rim at the rear is of marked advantage, for reasonsabove set forth, and besides allows free access to the vent duct for thepurpose of placement of the nuts employed to hold the seat hinge postsin -place, as'well as for cleaning purposes.

Also, by reason of the placing of the bowl outlet passage or trapfarther to the rear than usual, I secure ,a greater volume of water inthe bowl and trapand a proportionally greater resistance to the passageof sewer gas. v

When no local vent exists or is needed, the vent duct may be omitted,and-the other structural features and their inherentadvantages retained.Such a construction ;is disclosed in Figs. 4 and 5, and ginasnnich asthe vent duct is alone omittedtheiother parts V as in the other figures.

While the design of a closet around the novel featureslwhich I haveintroduced seem ingly dmits of but little change,'still it is evidentthat closets of types other than of the siphon jet class may besimilarly pro-v duced, and I do not, therefore, wish to be understood.as limiting myself thereto.

Having thus described my invention, what I claim is:
